MRI showed lesions on my brain. Multiple Sclerosis?

I had an MRI done only of my brain a week ago. My neurologist called for me to come in asap for results well it turns out i have lesions on both sides of my brain ranging from 1cm to 2.5cm. He said it looks like MS and he has ordered a second MRI of also my spinal cord to see if these lesions are also in my spinal fluid or something. Im scared he has not yet diagnosed me because he is waiting for the second MRI and possibly a lumber puncture.
My symptoms are: Dizziness, Blurred and double vision, Numbness in feet that have lasted for 1 month+, Muscle weakness, Memory and comprehension issues, Speech difficulties.

Does this sound like MS or am I worrying for no reason? Can something else cause brain lesions?
symptoms came on april 08 lasted until july 08 then came on again Dec 08 through to Jan now again July 09… still here I dunno if these count as episodes etc
